problem with cont for multi-threaded program

[Martin Percossi]

I'm having a problem debugging in gdb. It seems that when I press CTRL-C
to interrupt the program, gdb suspends or stops EVERY thread (of which
there are quite a few). When I type 'c' or 'continue', execution resumes
for that thread only. This means I must type c ( and return of course )
many times, which is no one's idea of fun. Searching the documentation,
I found out that you can apply a command to a list of threads. So I do:

thread apply all continue

to apply the command 'continue' to all threads.
But instead of resuming execution, I get (after several succesful
'continues' on some threads:

ptrace in stop_thread: Operation not permitted.

for one particular thread.

What's going on here?

TIA
Martin.
